(j)                                    A Person shall be deemed a “Beneficial Owner” of, and shall be deemed to “beneficially own,” any securities:

(i)                                     which such Person or any of such Person’s Affiliates or Associates beneficially owns, directly or indirectly;

(ii)                                  which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right or the obligation to acquire (whether such right is exercisable, or such obligation is required to be performed, immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (whether or not in writing) or upon the exercise of conversion rights, exchange rights, warrants, options, or other rights (in each case, other than upon exercise or exchange of the Rights); provided, however, that a Person shall not be deemed a Beneficial Owner of, or to beneficially own, securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange;

(iii)                               which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has or shares the right to vote or dispose of, or has “beneficial ownership” (as defined under Rule 13d-3 of the General Rules and Regulations under the Exchange Act) of, including pursuant to any agreement, arrangement or understanding (whether or not in writing); or

(iv)                              with respect to which any other Person is a Beneficial Owner, if the Person referred to in the introductory clause of this Section 1(j) or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (whether or not

4

in writing) with such other Person (or any of such other Person’s Affiliates or Associates) with respect to acquiring, holding, voting or disposing of any securities of the Company;

provided, however, that the preceding provisions of this Section 1(j) shall not be applied to cause a Person to be deemed a “Beneficial Owner” of, or to “beneficially own,” any security (A) solely because such Person has the right to vote such security pursuant to an agreement, arrangement or understanding (whether or not in writing) which (1) arises solely from a revocable proxy given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations under the Exchange Act, and (2) is not also then reportable on Schedule 13D under the Exchange Act (or any comparable or successor report), or (B) if such beneficial ownership arises solely as a result of such Person’s status as a “clearing agency,” as defined in Section 3(a)(23) of the Exchange Act; provided further, that nothing in this Section 1(j) shall cause a Person engaged in business as an underwriter of securities or member of a selling group to be a Beneficial Owner of, or to “beneficially own,” any securities acquired through such Person’s participation in good faith in an underwriting syndicate until the expiration of 40 calendar days after the date of such acquisition, or such later date as the directors of the Company may determine in any specific case; provided further, that the transfer of beneficial ownership of Common Shares to any Person without any consideration for such transfer being given by such Person shall not result in such Person becoming a Beneficial Owner of any additional Common Shares until the Person accepts such transfer; provided further, that a Person shall not be deemed to be a “Beneficial Owner” of, or to “beneficially own,” any Common Shares that would be issuable upon conversion of 2063 Debentures as a result of deferred interest, including compounded interest, accrued with respect to 2063 Debentures that are beneficially owned (and not yet converted) by such Person.  For the avoidance of doubt, it is understood that the exception in this Section 1(j) in the final proviso of the immediately preceding sentence does not apply to Common Shares attributable to deferred interest on 2063 Debentures that are delivered and beneficially owned on conversion of 2063 Debentures. Notwithstanding anything herein to the contrary, to the extent not within the foregoing provisions of this Section 1(j), a Person shall be deemed a “Beneficial Owner” of, and shall be deemed to “beneficially own” or have “beneficial ownership” of, any securities that are owned by another Person and that are treated, for purposes of Section 382 of the Code and the Treasury Regulations thereunder, as being (x) owned by such first Person (or by a Person or group of Persons to which the securities owned by such first Person are attributed pursuant to Treasury Regulation Section 1.382-2T(h)), or (y) owned by the same “entity” (as defined in the second sentence of Treasury Regulation Section 1.382-3(a)(1)(i)) as is deemed to own the securities owned by such first Person.
